    Its purely an api question. We could easily take the WNOHANG flag and
    just unset it when we get it and set O_NONBLOCK instead. We need
    O_CLOEXEC anyway though, and the only reason to do it would be to get
    rid of the O_ options and take only one type of flag (that and just a
    little more waitid consistency).
